The room, used by janitors for decades, houses the signatures of dozens of janitors dating back to 1907, the article stated.

According to the article, Terry Melvin, a building services worker at the university since 1988, has kept track of how many people have signed the door and estimates that roughly 110 different people have signed their names over the years.

"The earliest signature I found is that of ''C. S. Bateson'' or ''Creighton S. Bateson,'' who, along with his name, signed the year ''1907,''" Melvin explained.

Bateson''s signatures appear more times than any other name, prompting Melvin to dig a little deeper in to the history of the name, the article noted.

"I think some of them, like Creighton Bateson — whose signature is there maybe 10 times — just wanted to be remembered," said Melvin.

"They may not have buildings named after them or portraits of them on the walls, but all of the people who have signed their names in that closet have been part of the history of the university," Melvin added.
